Sodium ferrocyanide, identified by CAS 13601-19-9 and often referred to as yellow prussiate of soda, is a coordination compound of iron and sodium. It typically appears as yellow monoclinic crystals or powder and is highly soluble in water but insoluble in alcohol. While it contains cyanide groups, these are strongly bonded to the central iron atom, resulting in a chemical profile that is significantly less toxic than simple cyanide salts under normal conditions.
In industrial and research settings, this compound is valued for its chemical stability and specific reactivity. It serves as a precursor to various specialty chemicals and pigments. Proper handling is essential, as the material should be stored in a cool, dry environment away from strong acids to prevent the release of hydrogen cyanide gas. Its role as a versatile chemical intermediate makes it indispensable across diverse manufacturing sectors.
